  • I had that issue for months. There is no real solution afaik. Apparently, reading the NVM checksum is just not possible on Linux with this chip. It always defaults to 0xFFFFFF I believe. In theory you could write some value, to reset it, but it gave me some permissions error. I resorted to get the source of the kernel, patch out the checking code, compile just the module and then install it. I created a PKGBUILD for it, and I’m currently trying to make it a DKMS package, so you don’t have to reboot first to manually rebuild it.
    As you use Debian, you’ll need to create a manual compiling script, but here are my PKGBUILDs for reference: https://git.30p87.de/30p87/e1000e-nocksum-kerne Note that you need to swap out the kernel source link to the source of your current kernel version.

    The current problem is, that you need to reboot to update to a new kernel version, which then means the custom driver will not work anymore, and you need an internet connection to rebuild it, as it will need the most recent kernel version. So never kernel update without wifi in reach.

    I will first make it a DKMS package, to ease some of the pain, and then see if I can make it debian compatible.
